[sqlalchemy] Decoupling business and ORM model using dataclass(es)

Hi, When decoupling business from ORM model, dataclass passed to SA's imperative mapper *map_imperatively* will receive SA's internals like for example *_sa_instance_state* and *_sa_class_manager*. I am wondering, what would be the best way to have "pure" dataclass, without SA internals?
